Features/get bufr restructure

[ladsmund]

I have updated thet BUFR export functionalities to

• Parameterize relative sensor heights. Eg anometer relative to sonic ranger and barometer relative to gps to enable station specific configurations.
• Make it easier to (re)create BUFR files for specific timestamps
  • DMI requests missing BUFR files from downtime period
  • Testable code

In order to achieve that I have

• Organised the code Into three main modules:
  • bufr_utilities contains functionalities related to BUFR serialisation including both a read and write functions.
  • real_time_utilities contains functionality for filtering and selecting instantaneous data from time series.
  • get_bufr contains main scripts for generating bufr files AWS L3 csv data - aligning with out current operational pipeline.
• Implemented unit tests to ensure the updated version don't change the output.
• Parameterized get_bufr and restructured the use of global variables (WMO configs)
• Stoped using global context such as datetime.utcnow()

I have made a slight update to aws-operational-processing to provide explicit cli parameters since I removed the default paths.
